I already have problems with my B-button. My GP32 is just 3 weeks old, and I was
handling it extremely careful.
I don't know what happened, perhaps some little clip inside broke or detached, like
other GP32 users already reported. The button first started to feel different than the
A-Button, now it's already making annoying clicking noises when I push it. It feels
like it gets stuck inside the case for a split second before it pops out with a 'click'.
Until now it doesn't affect gameplay so much, but it keeps distracting me from playing
and gives me a certain displeasedness about my GP32, although I'm completely
happy with it otherwise. If it gets worse I'm probably going to open my GP32 to
see if I can fix it.
Perhaps it was just bad luck, and normally the GP32 buttons are fine. But I think that,
by and by, more people are going to have problems with them, since they seem really
fragile to me.
